Atari and UNIS have teamed up for another Pong arcade machine you can play at home, albeit one that's much smaller than UNIS' coffee table-sized analog models. The Mini Pong Jr has a 7.9-inch LCD screen and two classic dial controls so you can play with a friend. If you go it alone, you'll have ten difficulty settings to choose from. 

There’s no built-in battery, but you can install rechargeable AA batteries so you can play the machine anywhere. Alternatively, you can power the Mini Pong Jr with a USB cable and adapter.
